Vodafone India — vodafone outgoing calls will be stopped

Address:

411016

I have been using vodafone for 8 years, i have ₹34 in my account balance. Its the main sim i’ve been using for all my calls.
From the past few days i’m getting messages and calls saying after dec25, 2018 your outgoing services will be suspended and try to recharge with plans rs35/65/95 and get an extension of 28 days.
Though my sim validity when i checked a week ago, it is upto 2022, but now it is showing 24 nov 2018.
How could the company have the rights to deduct the validity of sim and how could it threaten the consumer to recharge with additional plans, when there is enough account balance in the sim card.
This is very annoying and depriving the rights of the consumer.
